"Assume Positive Intent" is what I just did the other day in an ambiguous online conversation. I could have gotten offended and reacted defensively, but I decided to give the other person the benefit of the doubt. It seems to have worked out.

My church had a young adult conference, and we started it off by signing a covenant for the weekend. There was a bit of discussion over how to deal with conflict and if people get offended. Someone else said "assume good intentions" and it was perfect.
